Open source BIOS/UEFI firmware
----------------------------

*This* new release, Canoeboot 20231103, released today 3 November 2023, is
based on the [Canoeboot 20231101](https://canoeboot.org/news/canoeboot20231101.html)
release - no Libreboot changes have been imported, in this release. The
previous Canoeboot release was [Canoeboot 20231101](canoeboot20231101.md),
released on 1 November 2023.

Canoeboot provides boot firmware for supported x86/ARM machines, starting a
bootloader that then loads your operating system. It replaces proprietary
BIOS/UEFI firmware on x86 machines, and provides an *improved* configuration
on [ARM-based chromebooks](../docs/install/chromebooks.html) supported
(U-Boot bootloader, instead of Google's depthcharge bootloader). On x86
machines, the GRUB and SeaBIOS coreboot
payloads are officially supported, provided in varying configurations per
machine. It provides an [automated build system](../docs/maintain/) for the
[configuration](../docs/build/) and [installation](../docs/install/) of coreboot
ROM images, making coreboot easier to use for non-technical people. You can find
the [list of supported hardware](../docs/hardware/) in Canoeboot documentation.

Canoeboot's main benefit is *higher boot speed*,
[better](../docs/linux/encryption.md) 
[security](../docs/linux/grub_hardening.md) and more
customisation options compared to most proprietary firmware. As a
[libre](https://writefreesoftware.org/learn) software project, the code can be
audited, and coreboot does
regularly audit code. The other main benefit is [*freedom* to study, adapt and
share the code](https://writefreesoftware.org/), a freedom denied by most boot
firmware, but not Canoeboot! Booting GNU/Linux/BSD is also [well](../docs/linux/) 
[supported](../docs/bsd/).

Canoeboot is maintained in parallel with [Libreboot](https://libreboot.org/), and by the same developer,
Leah Rowe, who maintains both projects; Canoeboot implements a more hardline
[zero-blobs policy](policy.md), in contrast to Libreboot's [Binary Blob
Reduction Policy](https://libreboot.org/news/policy.html). This means that
Libreboot supports *a lot more hardware*, but Canoeboot is provided for the
purists out there who are OK using slightly older hardware as a result.

Work done since last release
----------------------------

There have been no code changes whatsoever, on any of the current builds, but
a major oversight has been corrected.

Specifically, some binary blobs were *overlooked* by accident, in the previous
release and the one before that. The following binary blobs were present in
the last two releases, but have been deleted in *today's* release:

* `src/coreboot/default/3rdparty/stm/Test/FrmPkg/Core/Init/Dmar.h`
* `src/coreboot/fam15h_rdimm/src/vendorcode/intel/fsp1_0/baytrail/absf/minnowmax_1gb.absf`

Thanks go to Craig Topham, who reported this.

The Canoeboot 20231026 and 20231101 release tarballs will not be altered, but
errata has now been added to the announcement pages for those releases, to let
people know of the above issue.

Those files, listed above, have been removed in today's release.

Errata

### Update on 12 November 2023:

This file was also overlooked, and is still present in the release tarball:

* `src/vendorcode/amd/agesa/f12/Proc/GNB/Nb/Family/LN/F12NbSmuFirmware.h`

This has now been removed, in the Canoeboot git repository (`cbmk.git`), and
this file will absent, in the next release after Canoeboot 20231107. Thanks go
to Denis Carikli who reported this. The patch to fix it is here:

<https://codeberg.org/canoeboot/cbmk/commit/70d0dbec733c5552f8cd6fb711809935c8f3d2f3>
